What is a dsp radio?

DSP radio refers to the radio with the microprocessor DSP as the core.

DSP is a unique microprocessor (similar to an integrated circuit chip such as a computer CPU). Using digital signal processing technology, various functions of the radio are directly realized by software programming on the programmable general hardware platform. Including receiving, intermediate frequency processing, etc. This kind of radio needs no debugging and has good consistency. It can be extended to advanced functions such as single sideband, synchronous detection and secondary frequency conversion. This kind of radio with DSP chip as the core is called DSP radio.

This kind of radio breaks the circuit mode of the traditional radio, adopts the digital signal processing (DSP) chip of SILICON LABS in the United States to digitize the analog broadcast signal, and uses the modern software radio principle to process and demodulate it, which greatly improves the sensitivity, selectivity, signal-to-noise ratio and anti-interference ability.

Due to the adoption of digital signal processing technology, various functions of the radio, including receiving and intermediate frequency processing, can be realized directly on the programmable general hardware platform through software programming. This kind of radio does not need debugging, and its consistency is very good. It can be extended to advanced functions such as single sideband, synchronous detection and secondary frequency conversion without manual adjustment (the traditional AM/FM scheme may require four levels of manual adjustment).
